Abstract
The main objective of the article is to develop the concept of flock fragmentation and the averaging method for the application of electrocoagulation in the process of treating wastewater from coke ovens. The designed solution was part of an innovative system for the coke oven wastewater treatment process. The system is dedicated to removing the hazardous elements and compounds from wastewater from leaching ashes in municipal waste incineration plants. The design of the process and its automatization was based on a quantitative simulation method. The balance equations of mass, energy, and momentum of transport, complemented by the kinetics of the related reaction, are used during the calculation of the process. The main result achieved is a practical solution—the reactor’s scheme, classified due to a patent procedure in the Polish Patent Office.

A device dedicated to particle size distribution analysis—Analysette 2 made by Fritsch (Fritsch GmbH, Idar-Oberstein, Germany)—was used to analyze particle size after an electrocoagulation process
The electrocoagulation process was conducted in a mixing and non-mixing forced flow of liquid
Summary
Coke production requires a huge amount of water for the production process, and large amounts of contaminated wastewater are discharged into the environment. Coke wastewater is one of the most contaminated and toxic aqueous streams of waste and contains organic as well as inorganic pollutants [3,4,5]. They occur in large amounts, between 0.3 and 4 m3 per ton of coke [2,6]. The most important aspect is the development of new and more effective water treatment methods for this industry [6,7,8]
